Oh there is more to humanity than that. For example the history of europe with even yamnaya, corded-ware, EHG, ANF all looked different with different heights, skin tones, skull shapes, cultures, etc as well.
And this is from around 3000 BC. Modern european as you know it (admixture wise) would likely be fully formed at around 400 BC
